Ball Joint Extensions & Roll Center Adjusters | RX7 FC

  • Sale
  • Regular price $105.00 USD

A simple bolt-on solution to increase your front track width and improve roll center. This will improve turn-in and front grip while drifting. Increasing the front track also adds camber and increases inner wheel clearance on high-angle knuckle setups. We also offer caster offset versions, which add or remove a set amount of caster to give you the freedom to adjust the "self" steer to your driving preference.
